Xenon Levitation by Ralf Rudolph aka`Fairmagic

With this tool you are able to gently float small objects such as matches, feathers, playing cards, sponge balls or rubber bands etc. a few centimeters above the table.
Easy to build! Not for live situations! Use the gimmick for zoom, Instagram or similar. Also very suitable for demo videos to let business cards gently lift off.
Don't use it as a magic trick. Rather a physics experiment.
